In order to develop a more appealing cheeseburger, a franchise uses taste tests with 7 different
buns, 6 different cheeses, 2 types of lettuce, and 4 types of tomatoes. If the taste tests were done
at one restaurant by one tester who takes 10 minutes to eat each cheeseburger, approximately how
long would it take the tester to eat all possible cheeseburgers?
